This article provides a detailed classification of green and brown industries,as well as types of banks.Taking into account factors such as changes in carbon prices,application of carbon reduction technologies,government subsidies,and price transfers,a climate and environmental risk impact model was constructed.Stress tests were conducted on 20 commercial banks in China,and the impact of climate and environmental risks on their credit risk was evaluated.Furthermore,the heterogeneity of industries and banks was analyzed.The results show that the impact of climate and environmental risks on brown industries is significantly greater than that on green industries,while price transfer methods and national green subsidies can alleviate the impact on different types of industries.In addition,the loan value losses related to climate and environmental risks faced by different types of commercial banks have heterogene-ous characteristics,and the size of the losses is closely related to the quantity and industry distribution of credit disbursement.Mean-while,there is a significant difference in the ratio of loan value loss to core tier one capital among different types of commercial banks when impacted by climate and environmental risks,with state-owned banks having the highest loss ratio.
